Description

The old rubbish of disposing the landfill stacking is used for the hills saline-alkali wetland and plants the method for planting the bamboo willow

Technical field

The present invention relates to the old rubbish of in the past many decades landfill stacking as the disposal technology of fertilizer, the ecological, environmental protective field that belong to garbage disposal, fertilizer is made to combine with the forestry exploitation particularly relates to a kind of old rubbish of disposing the landfill stacking and plants the method for planting the bamboo willow for the hills saline-alkali wetland.

Background technology

China's formed track in each urban growth, annual ring just as the pine and cypress arboreal growth, another the enclosing the land of one circle stretches out, be called circuit, each circuit has all embodied the lead-time in a city, and each cycle is stayed next common, just similar garbage mountain or the refuse landfill of constituent.The house refuse in China city, (the comprising stacking field, flat area) of taking landfill method to process accounts for about 90%, and the house refuse accumulative total that landfill over the years is stacked has tens tons.Before 30 years, people can ignore to these garbage mountains or landfill yard because they still in the countryside, in the rural area; Before 20 years, these garbage mountains or landfill yard are enclosed into the city circuit, become one large " sight spot " in urban district, begin to cause that people pay close attention to, and new garbage mountain or landfill yard pitch of the laps outside circuit grow up (according to media report, outside the Fourth Ring, Beijing, outside the five rings, six rings are outer that hundreds of garbage mountains or landfill yard arranged); Nearly ten years, along with China's industrialization, urbanization paces are accelerated, urban population sharply expands, and garbage mountain or landfill yard scale are also increasing, reached the unaffordable stage in city (only the Area in Tianjin landfill waste just has up to ten million tons, takes up an area hundreds of mu).Much less big city, county town also are so (rubbish stacked of Yuncheng in Shandong county just have millions of tons, takes up an area more than 60 mu).Especially flat area, the land for building is in short supply, nowadays really is difficult to find the ground of landfill heap garbage.After past 30 years, 20 years, 10 years, nowadays those garbage mountains or landfill yard location have been the prime location in city.Though governments at all levels feel concerned about the people's livelihood, in the face of garbage mountain and the landfill yard of left over by history, very anxiety and helpless also seems.People look forward to the newly appearance of " the Foolish Old Man ", and with the spirit of " like the Foolish Old Man who removed the mountains ", move those garbage mountains and landfill yard allow these prime locations bring benefit to the people.How to dispose these old rubbish? burn obviously not become, because old refuse moisture is large, calorific value is low, refuses to burn, and does not calculate with combustion adjuvant cost height, moreover advances stove and how much come out of the stove almost or what, and residue is many, also need look in addition local landfill or stacking, loses more than gain.Facts have proved, to the disposal of new and old rubbish, the burning electricity generation mud of still heating up water no matter, not only the high loss of capital of cost is large, and dust and bioxin that burning produces all can serious environment pollutions.Up to the present, not yet find the old rubbish of harmlessness disposing, any feasible scheme of move original garbage mountain and landfill yard.The present invention is exactly to continue at us and utilizes house refuse, changing food waste, sludge of sewage treatment plant to make microbial organic fertilizer, and to guarantee no longer to produce after the new garbage mountain and landfill yard, complicated for old component of refuse, especially the building waste proportion is larger; Again through exposing to the sun and rain for many years, the nutrition volatilization, fertilizer efficiency runs off, compare with new rubbish composting, increase undoubtedly a lot of expenses, do not calculate economically, these actual conditions of innovative technology again, through careful investigation, find old rubbish through landfill or stack for a long time putrid fermentation slaking, realized the present invention, when those garbage mountains that i.e. disposal formed in the past or landfill yard, can prepare old rubbish with correlative, form the medium of bamboo willow special use, directly at the hills loessland, the drought and water shortage area, Low land, beach ground, wetland, all should not plant saline lands etc. on the soil of cereal crops, plant and plant ecological, environmental protective trees---the living bamboo willow of exceeding the speed limit, make our country green, develop forestry, work for the welfare of the people.

Summary of the invention

Goal of the invention: the specific function that the objective of the invention is the living bamboo willow of research and utilization ecological, environmental protective plant hypervelocity participates in the harmless treatment of original garbage mountain and the old rubbish of landfill yard, and promote the growth of bamboo willow with the old rubbish hole bed fertilizer that the correlative fermentation maturity makes that is mixed, thereby obtain significant environmental benefit, Social benefit and economic benefit.

It is the foundation of cultivation main body with selecting the bamboo willow that the present invention selects to prepare bamboo willow growth medium take old rubbish as carrier: be because the living bamboo willow of exceeding the speed limit not only has very high environmental value, economic worth, and have the specific function of ecology " drug abuse detoxifcation ", the old rubbish of harmlessness disposing.The bamboo willow new plant variety that to be the American the earliest generate with bamboo root and the grafting of willow branch, China develops " the living bamboo willow of exceeding the speed limit " that all be better than former female parent at aspects such as growing way, resistance, adaptability take former U.S. bamboo willow female parent as the basis.Because the root penetration power of bamboo is strong especially, adsorptivity and water imbibition are all fine again, lay a good foundation for generating fast tall and straight limb; Willow has plantation in China various places, and accommodative ability of environment is stronger, and its wood fibre is pliable and tough and pulling force is arranged.Therefore, have the gene of this two Plants by bamboo and willow in conjunction with the bamboo willow that generates, both had the tall and straight speciality of ability, trunk of bamboo Rapid Rooting, have again close, the tough and tensile and rich characteristics springy of willow cellulosic.Take the bamboo willow as the cultivation main body, have following advantage: one, bamboo willow possess hypervelocity and give birth to characteristics, and economic well-being of workers and staff is remarkable.It is adaptable, fast growth, and material is good, and multiple use is arranged.But 1 year jointing 〉=8 of bamboo willow meter; Increased slightly the diameter of a cross-section of a tree trunk 1.3 meters above the ground 〉=10cm in 2 years; Became a useful person in 3 years, and up to more than 12 meters, can be used as construction material; The large material of six year's harvest, height can grow to 20-25 rice, and the diameter of a cross-section of a tree trunk 1.3 meters above the ground can reach 42-50cm, and every strain can be produced the about 1M of the volume of timber ³By 6 year production cycle measuring and calculating, but one mu of bamboo willow extra earning more than 60,000 yuan every year on average.The branches and leaves of bamboo willow because of biomass and fuel value are very high can also be as renewable, free of contamination biofuel, be used for combustion power generation or gasification preparing biological diesel oil.Simultaneously, bamboo osiery wood and brush wood, as the paper pulp material in paper mill, natural whiteness can reach more than 60 degree, and pulping rate is up to 90%, considerably beyond common seeds such as traditional willow, willows.The valuable point of bamboo willow also is, no matter do paper pulp material, biofuel, still do construction material, the raw material of industry, every take turns the felling after the Second Year root again the president go out new talent, and growing way is more violent, 3-6 can cut down again again, can cut down continuously seven, eight times, and can grow seedlings pruning the branch that gets off every year again; Its two, bamboo willow adaptability is stronger, hills loessland, low-lying beach ground, wetland saline land all can be planted, and do not strive ground with grain, the land used cost is low, and can improve the saline land; Its three, the bamboo willow self has function of detoxification, can participate in the harmless treatment of rubbish, reduces the garbage disposal link, reduces the garbage disposal cost; Its four, the bamboo willow has anti-low temperature cold current, anti-saline and alkaline, waterlogging-resistant, anti-low light according to the characteristic of, high temperature resistant arid, also can normal growth in adverse weather condition and pH 〉=9, salinity exceed standard soil.This 4 point is exactly the cause that we select the bamboo willow.Because high yield has investment appeal, the present invention is the tool promotional value.Only having needs medium in large quantities, and garbage mountain and the landfill yard of the various places of could finally moving reach the purpose of purifying natural environmental.

Inventive principle: we find (1) in the survey, the bamboo willow grows in marshland (muddy pond) environment, well established and vigorously developing, vigorous, than other local grow all good, tracing it to its cause, is because such environment adapts to the exceptional function of habit of growth, growth mechanism and the growth thereof of bamboo willow most.So we have just had growing environment---the invention of " bamboo willow grown cultures foundation ditch bed " of making for the bamboo willow." hole bed " is rectangle, wide and deeply be 3 meters, length is not limit, and spread the malthoid antiseep in hole bed bottom and inwall, after old rubbish and soil were mixed in by volume 2: 1, add slaking humic acid (becoming thoroughly decomposed through sodium hydroxide and sodium silicate processing), nourishing additive agent and click and enter anaerobic species and mix thoroughly to put into and cheat bed, pour water again, the plastic covering film carries out anaerobic fermentation, is to make the hole bed culture medium.Why spread malthoid, lid plastic foil, malthoid can prevent that old garbage leachate from polluting Soil Surrounding and underground water source first; But the rear plastic covering film secluding air of second pouring water, thereby create conditions for anaerobic fermentation; Three points are joined anaerobic species and can be impelled the compound fermentation maturity to kill pathogen and improve fertilizer efficiency.(2) utilize the cultivation of ecological, environmental protective plant bamboo willow to participate in old rubbish processing to be harmless, because bamboo willow well developed root system, rhizosphere circle growing a large amount of aspergillus nigers and fiber decomposing bacteria have decomposition to hydrogen based compound, polyethylene, polypropylene in oneself the fermentation rubbish; Heavy metal, bioxin in the rubbish also can be dissolved, be eliminated in the organic solvent of plant rhizosphere secretion and decomposed utilization.(3) habit of growth and the old rubbish according to the bamboo willow exposes to the sun and rain throughout the year, the nutrition volatilization, the actual conditions that fertilizer efficiency runs off, and the growth of bamboo willow happiness salt, happiness is wet, happiness is organic abundant, to sodium, calcium, silicon, manganese, zinc, boron, iron, the psychological need that the elements such as copper are comparatively responsive, when making the hole bed culture medium, add as one feels fit and become owner of nutrients of nitrogen (such as urea), phosphorus (such as rock phosphate), potassium (such as potassium chloride) and silicon, sodium is (such as sodium hydroxide, sodium silicate aqueous solution) and manganese (such as manganese sulphate), zinc (such as white vitriol), calcium (such as quicklime), boron (such as borax), iron (such as ferrous sulfate), the nourishing additive agent of copper (such as copper sulphate) configuration, the medium that makes like this, be equivalent to impel the bamboo willow to accelerate to become a useful person for the growth of bamboo willow provides special fertilizer.
